Hi
Andy,
Otgiva is a Low
German form of the Old
German name Ottogeba (other forms: Ottogebe, Ottegeba, Ottegebe).
The element "geba" is the Old
German word for 'gift'.
In Low
German the letter b very often becomes v/w instead.
In modern High
German the b was kept (
Gabe, geben), while in other Germanic languages it's v/f instead:
English: gift, give
Swedish: gåva, giva
Danish: gave, give
Low
German: Gaav (even Gifft), geven
Hope that helps?
Regards,
Satu
